World's Largest Scale Model of the Solar SystemThe Sweden Solar System is the world's largest model of our planetary system, built at a scale of 1:20 million and stretches the entire length of the country. The Sun is represented by the Globe arena in Stockholm, the largest spherical building in the world. The planets are placed and sized according to scale with the inner planets being in Stockholm and Jupiter at the International airport Arlanda. The outer planets follow in the same direction with Saturn in Uppsala and Pluto in Delsbo, 300 km from the Globe. The model ends at the Termination shock, 950 km from the Sun.
At each planet station, exhibits provide information about astronomy and the natural sciences, and also about related mythology and culture. The Stockholm Visitor's Board (former Stockholm Information Service) was a sponsor of the project in the beginning, like several museums, theaters, parks and scientific institutions.
An elaborate model of the Moon (18 cm in diameter) is on display in another part of the museum.
Jupiter (7.3 m in diameter) is placed at the roundabout near Sky City, in Stockholm's large airport Arlanda 40 km from the Globe. Made as a flower decoration, with different flowers representing different zones of the giant gas planet; however, there are plans to build a 3D model.
Saturn (6.1 m in diameter) is placed outside the old observatory of Anders Celsius, in the so-called Celsius Square, at centre of Uppsala, 73 km from the Globe.
Uranus (2.6 m in diameter) was vandalized and the new model is planned to some place in Gävle, 143 km from the Globe.
